I think the answer is C. Auxiliary verb 'are' does not need to be repeated.

Lets simplify this sentence.
Many biological traits are not X,modifier but Y.
Now remove not...but part.
Many biological traits are Y.

No problems right??...So 'are' doesnt need to be repeated.
C it is.

A can't be the answer as Stephen has not argued abt two different things but two different points abt the same thing.

Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored due to their enhancement of reproduction or survival, but that they are simply random by-products of other evolutionary developments.
A due to their enhancement of reproduction or survival, but that they are
B due to the reproduction or survival they enhance, but they are
C because they enhance reproduction or survival, but
D because they enhance reproduction or survival, but are
E because of enhancing reproduction or survival, but are


this one is kinda tough. I go for D. I think are is needed after but to refer to biological traits b/c Biological traits are not x but are y.

For whomever asked about A. A has "their" in it. Their doesn't refer correctly to biological traits.

I chose C for this very same reason. Do we know what the OA is?

C because they enhance reproduction or survival, but
D because they enhance reproduction or survival, but are
E because of enhancing reproduction or survival, but are


vote: C

Originally thought D...but the idiom should be "not x...but y" which makes me believe the answer is C.
